This refurbished Cisco C9300-48UXM-A is a Catalyst 9300 Series 48-port multigigabit stackable access switch running the Network Advantage feature set. Professionally tested and reset to factory defaults, this unit delivers the full production capability of a new unit at a fraction of the cost. The C9300-48UXM-A ships with 36 ports operating at 100 Mbps, 1G, or 2.5G and 12 ports operating at 100 Mbps, 1G, 2.5G, 5G, or 10G — all 48 ports supporting Cisco Universal Power over Ethernet (UPOE) with a 490 W PoE budget. A single modular uplink slot accepts optional network modules for 1G, 10G, 25G, or 40G uplink connectivity.Built on Cisco's UADP 2.0 ASIC, the C9300-48UXM-A delivers 580 Gbps of switching capacity and 431.54 Mpps forwarding performance. Cisco StackWise-480 technology enables stacking of up to eight units with 480 Gbps of dedicated stacking bandwidth, forming a single resilient logical switch. The platform runs Cisco IOS XE with an x86 CPU architecture, supporting full Layer 3 routing — including OSPF, EIGRP, BGP, IS-IS, and policy-based routing — as well as SD-Access, MACsec-128 hardware encryption, Flexible NetFlow, VXLAN, TrustSec, 802.1x, and model-driven programmability via NETCONF and RESTCONF.
At $1,949, this refurbished C9300-48UXM-A represents significant savings versus new list pricing while delivering identical enterprise functionality. WhaleyComm is ISO 9001, R2v3, and e-Stewards certified with 25+ years of experience and 5,000+ enterprise customers — every unit ships with our Lifetime Warranty and a Certificate of Testing.

Ideal Use Cases
High-Density Wi-Fi 6 and Wi-Fi 6E Access Layer
All 48 UPOE ports deliver up to 60W and multigigabit speeds, making the C9300-48UXM-A ideal for powering and connecting Wi-Fi 6 and Wi-Fi 6E access points at 2.5G or 10G without infrastructure upgrades.
Enterprise Campus Access Switch
StackWise-480 stacking with up to eight units and 480 Gbps of dedicated stack bandwidth enables high-density campus deployments to operate as a single logical switch with sub-50ms failover.
SD-Access Fabric Edge Node
The C9300-48UXM-A serves as a validated SD-Access fabric edge node, supporting TrustSec group-based policies, VXLAN segmentation, and Cisco DNA Center integration for intent-based network automation.
High-Power IoT and IP Camera Aggregation
With 60W UPOE available on all 48 ports and a 490W PoE budget expandable to 1,590W with a second power supply, this switch is well suited for aggregating power-hungry IoT devices, PTZ cameras, and smart building endpoints.
Multigigabit Workstation and Collaboration Endpoint Access
The 12 native 10G/mGig ports and 36 2.5G ports provide workstations, video-conferencing endpoints, and compute nodes with bandwidth well beyond standard gigabit, eliminating uplink congestion at the access layer.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The suffix indicates the software license tier included with the hardware. The -A model includes the Network Advantage license, which enables advanced features such as BGP, OSPF, VXLAN, TrustSec, MACsec, and SD-Access fabric roles. The -E model includes the Network Essentials license with a reduced Layer 3 and security feature set. Both models use identical hardware.
No. Per Cisco's default configuration, the C9300-48UXM-A does not include a network module in the uplink slot. The modular slot supports optional Cisco C9300 network modules including the C9300-NM-4G (4x1G), C9300-NM-8X (8x10G), C9300-NM-2Q (2x40G), C9300-NM-2T (2x25G), and C9300-NM-4M (4xmGig). Contact our team to add a compatible module to your order.
Yes. The C9300-48UXM-A supports Cisco StackWise-480 and can be stacked with any combination of standard Catalyst 9300 modular uplink models (C9300 SKUs) in a stack of up to eight units. Mixed stacking with Catalyst 9300X models is also supported at StackWise-480 speeds. Fixed uplink C9300L models cannot be mixed into the same stack.
Yes. Every WhaleyComm unit ships with a Lifetime Warranty. If it fails under normal operating conditions at any point, we replace it at no cost — no time limits, no questions asked.
